The US health care system is a very well run billing machine with average (compared to other developed nations) health outcomes as a lucky side-effect.

I pay $6000+/year in health insurance in the US + deductibles + co-pays + + + and I don't even know if they'll cover me when shit really hits the fan - but hey, I'll get a flu shot "for free".

Check profit margins for companies in the health care space, they're pretty good.
